Triggering apparatus for rotating-frame animal trap
A triggering apparatus for a rotating-frame animal trap including a collapsible enclosure capable of supporting the trap in set position in alignment with the enclosure entrance, the enclosure having a separate bait container mounted within its interior and a triggering lever extending within the bait container, whereupon movement of the lever within the bait container causes rotation of a release shaft that frees a catch holding the trap in set position, thereby firing the trap and pinning the animal within the trap's rotating jaws. The catch includes a detent that holds the jaws of the trap in set position against the body of the enclosure adjacent its entrance, such that the animal must pass through the set jaws of the trap in order to access the bait container. The bait container is constructed with a restricted opening of substantially smaller compass than the entrance of the enclosure so as to permit access only by a smaller animal's paw, and prevent such animals, as dogs, from triggering the trap with their snout.
The present invention relates generally to the field of animal traps, and more specifically to the art of triggering devices for use in connection with so-called “instant kill” animal traps of the rotating-frame type.
Many attempts have been made over the years to develop an animal trap that will effectively and humanely dispose of certain animals, such as raccoons, which continue to pester farmers and the like by destroying vegetation, poultry and other small animals. Since such animals are generally paw-feeders that use their paws to reach for and grasp their food, a number of spring-loaded “leg-hold” type trapping devices have been developed which are designed to clamp down on the leg of the animal upon triggering same. Devices of this type are disclosed in U.S. Pat. Nos. 6,658,787; 4,802,301; 4,483,093; and 4,158,929. These devices, while somewhat effective, are disadvantageous in that the trapped animal will oftentimes suffer a long and slow death, or self-mutilate its own extremities in an attempt to free itself.
The rotating-frame type animal trap, also commonly named the “Conibear” trap after its original inventor, is generally considered to be more effective and humane in that it is designed as an “instant kill” device. This trap is designed with a pair of metal rectangular frames or jaws that are cooperatively hinged midway and spring-loaded for rapid and forceful closure upon actuation. Upon actuation, the jaws are intended to snap shut on the animal's spinal column at the base of the skull, thus causing instant death.
Conventionally, as a means for triggering a rotating-frame trap, one jaw will carry a baited trigger that extends into the passageway created by the jaws, and the other jaw has a catch element that holds the trap open in its set position. However, with this conventional triggering device, it is impossible to control the size, species, or direction of the animal entering the trap. Since the trap is designed and intended to clamp down on the main body or torso of the animal, its passageway is large enough to accommodate the head and/or body of other larger animals that are also lured to the bait. Consequently, domestic animals and pets, such as dogs, are frequent victims of this type trap.
The indiscriminate nature of the above conventional triggering means has been a long-standing and continuing problem that persists to this day. In those areas where trapping is still prevalent, numerous veterinary reports are available showing continued findings of domestic animals and pets that have unwittingly found there way into the deathly grip of the jaws of such traps. It is with this in mind that I have come to conceive of and develop my improved triggering device for use in connection with such rotating-frame traps, which will become more apparent from the description to follow, particularly when read in conjunction with the accompanying drawings.
BRIEF SUMMARY OF THE INVENTIONIn accordance with the present invention, my improved triggering apparatus for a rotating-frame animal trap utilizes an enclosure separate from the trap that is capable of supporting the trap in set position with the passageway through the jaws of the trap positioned in general alignment with the entrance to the enclosure. Importantly, the conventional triggering device used in connection with such traps, which typically extends into the passageway of the trap, is removed so as not to obstruct the enclosure entryway.
Mounted within the interior of the enclosure is a separate bait container having an opening thereto which preferably faces the entryway to the enclosure. The opening-defining portions of the bait container are of substantially smaller compass than that of the enclosure entryway, having major dimensions suitable only for accommodating the relatively small arm of a raccoon, opossum or other like “paw-feeding” animal.
Mounted atop the enclosure is a catch mechanism that includes a detent member for engaging and holding the jaws of the rotating-frame trap in set position against the body of the enclosure. The detent member is pivotally mounted near the front of the enclosure and extends outwardly and downwardly therefrom toward the enclosure entryway, thereby defining a channel or space between it and the enclosure which is appropriately sized to accommodate and hold the jaws of the trap.
A detent actuating shaft is pivotally connected to the detent member and extends rearward therefrom toward a catch release mechanism. The detent actuating shaft is axially movable between a forward “closing” and a rearward “opening” detent position, and is positioned for releasable engagement by the catch release mechanism when the triggering apparatus is supporting the trap in its set position prior to actuation.
The catch release mechanism includes a release shaft rotatably mounted to the enclosure with a triggering lever extending radially outward therefrom and into the inner confines of the bait container. The release shaft extends upwardly toward and connects to a release catch or “dog” that may be set with variable sensitivity for releasable engagement of the catch mechanism that holds the trap in its set position. The release dog functions to hold a freely rotatable trigger gate stationary, which in turn releasably engages the detent shaft of the catch mechanism and holds the same in its “closed” detent position pending actuation of the triggering device.
To set the triggering device and rotating-frame trap, the trigger gate of the catch release mechanism may be set with the release dog at the desired sensitivity. The rotating-frame trap may also be set by any conventional means to its spring-loaded firing position. With the triggering device set, the pre-set rotating-frame trap, ready for actuation, may then be mounted on the enclosure adjacent its entryway with the jaws of the trap sandwiched between the enclosure body and detent member, and in proper alignment to permit passage therethrough.
The force of the trap jaws will then push against the detent member of the catch mechanism, causing the detent actuating shaft to bear firmly against the trigger gate in readily releasable relation.
Once set, actuation of the triggering device requires an animal to enter the enclosure through its entryway, and consequently through the passageway of the rotating-frame trap. Actuation of the triggering device and trap cannot occur, however, unless and until the animal is capable of reaching its arm through the restricted opening of the bait container, which is notably too small for the snout of a domestic animal, such as a dog. Upon reaching for the bait, the inquisitive “paw-feeding” animal will pull the trigger lever forward toward the opening of the bait container, thereby causing rotation of the release shaft. This, in turn, rotates the release dog, thus freeing the trigger gate which holds the detent actuating shaft and detent member in closed position. With the detent member free to rotate to an open position, the jaws of the trap are also free to rotate, and will rapidly and forcefully close upon the animal.
Preferably, as a means of convenience to facilitate storage, packaging and transportation of my new triggering device, the enclosure body may be configured from a plurality of exterior frame sections that are constructed to be collapsible. Although this may be accomplished by any known means, it is presently contemplated that selected frame sections may include snap-lock brackets designed for ease of dismantling and securing the same together to form the enclosure. With such construction, the triggering device may be readily broken down for ease of packaging and shipment, and can be readily transported and reconstructed in the field, when and where desired.
BRIEF DESCRIPTION OF THE DRAWINGSThese and other objects and advantages of the invention will more fully appear from the following description, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
As shown in
Mounted atop enclosure 1 on cross-panels 9 and 11 is a catch mechanism 25 that includes a detent member 27 for engaging and holding the jaws 21 and 23 of the rotating-frame trap 13 in set position against the front cross-panel 11 of the enclosure 1. The detent member 27 is pivotally mounted via pivot pin 31 to an extension bracket 29 which is fixed to and extends outward and forward from the front cross-panel 11 of the enclosure 1. When the catch mechanism 25 is in set position, as shown in
As shown further in
Due to differing design configurations of jaws 21 and 23 for certain makes of rotating frame traps, the distance between jaws 21 and 23 may vary. As best shown in
Of course, as bracket 29 is adjusted forward or rearward, the length of the detent actuating shaft 35 must also be correspondingly adjusted, as it is important to maintain the positioning of detent member 27 in substantially parallel relation to the front of enclosure 1 when supporting trap 13 in its set position. Failure to do so may cause inconsistency in the operation of triggering apparatus 1 and/or premature triggering of the trap 13. As shown best in
As shown best in
As shown best in
Notably, the release dog 47 may be set with variable sensitivity to adjust the desired force necessary for release of trigger gate 49 and catch mechanism 25 that holds the trap 13 in its set position. To adjust the sensitivity, release dog 47 may be rotated slightly to alter the degree of engagement between the notched portion 48 of dog 47 and the trigger gate 49, thereby increasing or decreasing the amount of necessary rotational movement of shaft 45, and consequently dog 47, to release trigger gate 49.
As seen in
The bait container 51 also includes a side slot 61 through which the free end of a triggering lever 63 extends. Preferably, triggering lever 63 extends within the confines of the bait container 51 substantially all the way across the opening 53, leaving only a small clearance between its free end and the sidewall of the container 51, so as to be disposed within the pathway leading from the opening 53 to the rear of the container where the bait is to be placed. As seen in
In operation, one using my improved triggering device will preferably first set the jaws 21 and 23 of the rotating-frame animal trap 13 to their spring-loaded firing position, utilizing the trap's spring locking clamps 65 and 67 in a conventional manner to hold the jaws in set position prior to loading the trap 13 onto the triggering device 1. With the trap 13 set, the triggering device 1 may then also be set to its triggering position, as shown in
The operation of my improved triggering apparatus upon actuation is best described in reference to
Upon reaching for the bait, the inquisitive “paw-feeding” animal must push its paw past the trigger lever 63 to access the bait 69 which is located near the rear of the bait container 51. As shown in
Notably, enclosure 1 of the triggering apparatus is preferably constructed to be collapsible into a plurality of exterior frame sections as a means of convenience to facilitate storage, packaging and transportation thereof. As shown in
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of the invention which comprises the matter shown and described herein and set forth in the appended claims.
